8.0.9 folder missing in release notes

https://github.com/dotnet/core/tree/main/release-notes/8.0

8.0.10 and 8.0.8 exists, specifically looking for the 8.0.400 release note which I expected to find there but the release note for 8.0.8 mentions the following

The .NET 8.0.8 and .NET SDK 8.0.400 releases are available for download.
https://github.com/dotnet/core/blob/main/release-notes/8.0/8.0.8/8.0.8.md
Why is there no 8.0.400.md in that folder then?

Release date for the individual releases aren't present in release.json
https://github.com/dotnet/core/blob/main/release-notes/8.0/8.0.8/release.json
Just says "release-date": "2024-09-24" but that's not true for all SDK versions listed in the document like 8.0.400 released on the 13:th of August.
